The Spring Cultivation Method of plum blossom (Plum Blossoms)
The plum blossoms that stretch their branches in the biting cold of spring always add a touch of proud and elegant posture to the courtyard. As a representative of early spring flowers, plum blossoms have unique needs for care during their growing period. Mastering the correct spring care methods can not only promote bud differentiation but also lay the foundation for the entire year's growth.
I. Nutrition Supply Management
Combination of Organic Fertilizer and Compound Fertilizer
When the potting soil lacks basic fertilizer, it is recommended to water with a diluted sesame cake fertilizer solution at a ratio of 1:10. When the new roots have grown to about 5cm, switch to using phosphorus and potassium compound fertilizer granules, buried shallowly 3-5 granules around the pot edge, allowing natural dissolution with spring rain for better absorption.
Fertilization Cycle Control
Supplement liquid fertilizer every 15-20 days, taking care to avoid getting fertilizer solution on the leaves. Before the onset of the rainy season in the south, additional slow-release fertilizers containing calcium and magnesium elements can be applied to enhance resistance to adversity.
II. Art of Water Regulation
Precise Watering Principle
Use the 'dry-wet' method, watering thoroughly when the surface soil turns white. In the north, it is recommended to water early in the morning, combined with weekly loosening of the soil to maintain root ventilation. For potted plum blossoms, the bamboo stake insertion method can be used to check moisture; if the soil adhering to the bamboo stake is moist, stop watering.
Drainage and Flood Prevention Measures
Check the pot bottom holes before the rainy season arrives and raise the pot by 2-3cm to promote drainage. For ground cultivation, dig circular drainage ditches to prevent积水 that could lead to root rot.
III. Principles of Shaping and Pruning
Scientific Pinching to Promote Flowering
When new shoots reach 15cm, retain 3-4 pairs of leaves and pinch the tip to stimulate the differentiation of lateral buds. Focus on dealing with vertical and rapidly growing branches, as retaining oblique growing branches is more conducive to the formation of flower buds.
Techniques for Bud Point Management
During the germination period, promptly remove overlapping buds, retaining 2-3 full bud points per branch. Old stems can retain a few adventitious buds to cultivate new shaping branches.
IV. Disease Prevention System
Biological Control First
Hang yellow sticky insect boards to control aphids, and release ladybugs to control scale insects. Regularly spray garlic extract to enhance plant disease resistance.
Chemical Control Essentials
Starting from the end of April, alternately use carbendazim and mancozeb, focusing on spraying at the branching points of the branches. After rain, promptly reapply, ensuring the concentration of the pesticide does not exceed 800 times dilution.
By following these verified care methods, your plum blossoms will bloom more luxuriantly next year. Remember to observe the subtle changes in the plants and adjust management measures accordingly, allowing this friend of the cold season to show vitality in the spring breeze.
